ABSTRACT

The present invention relates to a liquid lip stick container having a configuration in which, an ascending/descending guide member is rotated together when a user rotates a container body while holding a support, so that a pumping guide member is lifted up/lowered, thereby performing a pumping operation. Thus, the container can discharge liquid contents through a simple structure, and thus can improve usability when contents are applied through an upper applicator.

BACKGROUND OF THE INVENTION

The present invention disclosed herein relates to a liquid lipstick container, wherein a liquid lipstick container has a configuration in which an ascending/descending guide member is rotated together when a user rotates a container body while gripping a support body, such that a pumping guide member is lifted up/lowered, thereby performing a pumping operation. Thus, liquid contents are discharged through a simple structure, which improves usability when contents are applied through an applicator at an upper portion of the container.

Generally, a solid lipstick is configured to lift/lower a solid stick to the outside of a container by rotating a lower portion of the container after opening a cover thereof. For example, when using a lipstick, a user first opens the cover of a container, protrudes the stick out by rotating a lower portion thereof, and lowers the stick to be received into the container after using.

However, this type of solid lipstick has a problem wherein its ingredients are easily spoiled by contact with outside air.

In addition, another type of lipstick, which is used by spreading a liquid lipstick onto a brush like spreading a nail polish, also has a problem of hardening easily by contact with outside air.

To solve the problems as the above, “liquid lipstick container” is disclosed in the registered utility model patent no. 20-0367724 (hereafter called as the registered utility model patent).

The registered utility model patent relates to a liquid lipstick container, the liquid lipstick container comprising: a liquid lipstick receiving tube (10) receiving a liquid lipstick; a piston (20) pressurizing the liquid lipstick received in the liquid lipstick receiving tube; a piston rod (30) pushing the piston (20) and pressurizing a liquid lipstick (M); an operation housing (40) operating the piston rod (30); a brush supporting cap (50) supporting a lipstick brush (51); and a cap (20) sealing the lipstick brush (51),

wherein the liquid lipstick receiving tube (10) is characterized to be equipped with a pair of elastic leg parts (11) having a screw part (13) at an inner side of a lower end thereof and an outward protrusion (12) at an outer side end thereof, wherein the piston rod (30) comprises a screw part (32) screw-coupled to the elastic leg part (11) and an operating protrusion (33) at a lower end thereof, wherein the operation housing (40) is characterized to comprise an operating rib (41) at an interior so as to push the operating protrusion (33).

The registered utility has a structure wherein as a piston rod (30) ascends by the rotation of the rotation of an operation housing (40), a piston (20) coupled with a globular protrusion (31) at an upper end of a piston rod (30) moves in an upward direction and discharges liquid contents by squeezing. To squeeze contents out, the lipstick container should be equipped with an operating rib (41), an operating protrusion (33), a pair of elastic leg parts (11); therefore, the structure of the lipstick container becomes complicated, thereby resulting in a problem a complicated assembly process and a high manufacturing cost.

In addition, a space for the length of a piston rod (30) should be secured; therefore, the lipstick container gets bigger in size, thereby resulting in a problem of not being easy to carry.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals provided in the drawings indicate the same members.

FIG. 1 is an exploded perspective view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention. FIG. 2 is an assembled perspective view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention. FIG. 3 is a cross-sectional view illustrating a configuration of a liquid lipstick container according to an exemplary embodiment of the present invention.

Referring to FIGS. 1 to 3, a liquid lipstick container according to an exemplary embodiment of the present invention may include a container body 100, an ascending/descending guide member 200, a pumping guide member 300, a support body 400, and an applicator 500.

The container body 100 storing liquid contents is configured to have a volume getting reduced according to a use of the contents, and simply saying, the container body 100 may equip a piston 110 which ascends according to a use of the contents inside of the content body 100. Additionally, it is possible that the container body 100 has a configuration wherein an inner container made of soft material that is absorbed according to a use of contents can be coupled separately inside the container body 100.

In the present invention, it is characterized that the container body 100 is configured to be rotated in a state that a support body 400 to be described later is gripped. When a user rotates the container body 100, a pumping guide member 300 can be ascended/descended by rotating an ascending/descending guide member 200 together which is coupled at an upper portion of the container body 100.

Meanwhile, at an upper portion of the container body 100 is coupled an over cap 800 which encases the support body 400 and the applicator 500 so as to prevent the support body 400 and the applicator 500 from being broken by a foreign material flowing through a discharging hole 511 or by an external pressure.

The ascending/descending guide member 200, coupled to an upper portion of the container body 100 and rotating together when the container body 100 rotates, is equipped with a content inflow part 210 forming a content inflow hole 211 at an inner center portion thereof such that the contents stored in the container body 100 can flow in. At the content inflow part 210 is equipped a first check valve 212 which is installed at an upper portion of the content inflow hole 211 and opens/closes the content inflow hole 211 according to a pressure change of the content inflow part 210.

Furthermore, at the content inflow part 210 is coupled a sealing member 700 which seals a space separated between the content inflow part 210 and a content suction tube 320 to be described later. An outer circumferential surface of the sealing member 700 is closely contacted to the content inflow part 210 and an inner circumferential surface thereof is closely contacted to the content suction tube 320, such that the sealing member 700 seals the space separated between the content inflow part 210 and the content suction tube 320.

In the present invention, it is characterized that at an upper portion of the ascending/descending guide member 200 is equipped an ascending/descending guide protrusion 220 which ascends/descends a pumping guide member 300 to be described later by rotation of the ascending/descending guide member, wherein a pair of ascending/descending guide protrusions 220 are protrusively formed alternately above and below along the perimeter of an upper end of the ascending/descending guide member 200 and guides a movement of a pumping guide protrusion 310. When the pumping guide protrusion 310 moves form a bottom dead point 312 of the ascending/descending guide protrusion 220 to a top dead point 311 thereof, the pumping guide member 300 ascends, whereas when the pumping guide protrusion 310 moves from a top dead point 311 of the ascending/descending guide protrusion 220 to a bottom dead point 312 thereof, the pumping guide member 300 descends, thereby achieving an ascent/descent of the pumping guide member 300.

Meanwhile, it is possible that the ascending/descending guide protrusion 220 can be configured in a way that the container body 100 can be rotated to both directions. However, it is preferable to be rotated to one direction for operational stability e.g. not to easily discharge contents by rotating the content body 100 by an external pressure during the period of storing or not to store contents with a check valve opened. For this purpose, at both sides of the bottom dead point of the ascending/descending guide protrusion 220 is formed a protrusion 221 for preventing a reverse rotation of the container body 100.

The pumping guide member 300 ascended/descended by the rotation of the ascending/descending guide member 200 changes an internal pressure of the content inflow part 210 and induces a pumping operation, further comprising a pumping guide protrusion 310, a content suction tube 320, and a valve installation part 330.

A pair of the pumping guide protrusions 310 protrusively formed at both sides of the pumping guide member 300 are secured at an upper end of the ascending/descending guide protrusion 220, and move along an upper side face of the ascending/descending guide protrusion 220 when ascending/descending guide member rotates. At this time, the pumping guide protrusion 310 can be inserted to a vertical guide groove 420 formed at an inner side of the support body 400 and move vertically.

The content suction tube 320, which ascends together as the pumping guide protrusion 310 ascends and sucks the contents stored in the container body 100 by changing an internal pressure of the content inflow part 210, has a tube shape with an inner part empty such that contents can move through.

The content suction tube 320, which ascends/descends in a state that an outer circumferential surface thereof is closely contacted to the sealing member 700 and makes it possible for a first check valve 212 to open/close a content inflow hole 211 by changing an internal pressure of the content inflow part 210, pressurizes an upper end of the first check valve 212 in a state that the pumping guide member 300 is descended and thereby prevents the first check valve 212 from being opened.

The valve installation part 330 forms a space which stores contents moving to an upper portion thereof through the content suction tube 320 and has a second check valve 331 installed so as to open/close an opened upper end of the content suction tube 320, wherein the second check valve 331 closes the open upper end of the content suction tube 320 when the pumping guide member 300 ascends, whereas the second check valve 331 opens an open upper end of the content suction tube 320 by the pressure of contents when the pumping guide member 300 descends.

Meanwhile, at an upper portion of the pumping guide member 300 are installed a content moving part 600 which connects the pumping guide member 300 and an applicator 500 such that contents flowing in the valve installation part 330 can move to the applicator 500. The content moving part 600 comprises a coupling part 610 which is coupled to an upper portion of the pumping guide member 300, and a content moving tube 620 which extends from the coupling part 610 and is coupled to a discharging tube 520 of the applicator 500 so as to be ascended/descended and forms a space where contents moves.

The content moving part 600 equips a hollow such that the contents flowing into the valve installation part 330 can move to the applicator 500.

Furthermore, at an upper portion of the pumping guide member 300 is equipped a spring (S) which is disposed encasing the content moving part 600 at an outer side of the content moving part 600, and provides an elastic force to a downward direction during the process when the pumping guide protrusion 310 moves from a top dead point 311 of the ascending/descending guide protrusion 220 to a bottom dead point 312 thereof and causes the pumping guide member 300 to descend. A lower end of the spring (S) is secured to an upper portion of the pumping guide member 300 while an upper end thereof is supported by an upper inner side of the support body 400, such that the spring (S) contracts when the pumping guide protrusion 310 ascends along an upper side face of the ascending/descending guide protrusion 220, and stretches when the pumping guide protrusion 310 descends along an upper side surface of the ascending/descending guide protrusion 220, thereby providing an elastic force to the pumping guide member 300.

The support body 400, which is coupled at an upper portion of the container body 100, encasing the ascending/descending guide member 200 and the pumping guide member 300, forms a hollow 410 at an upper portion thereof such that the applicator 500 can be coupled and a vertical guide groove 420 which guides a vertical movement of the pumping guide protrusion 310.

The applicator 500, which is coupled to the hollow 410 of the support body 400 and applies contents to a user's lips, comprises an application surface 510, wherein the application surface 510 has a discharging hole 511 at a center portion thereof such that contents can be discharged through.

Furthermore, at an inner upper side of the applicator 500 is equipped a discharging tube 520 which extends to a downward direction such that the content moving tube 620 of the content moving part 600 can be coupled so as to ascend/descend.

Hereinafter, referring FIGS. 4 to 6, an operational process of a liquid lipstick container according to an exemplary embodiment of the present invention will be explained. FIGS. 4 to 6 are views illustrating an operational state of a liquid lipstick container according to an exemplary embodiment of the present invention. FIG. 7(a) to FIG. 7(c) is a view illustrating a process wherein a pumping guide protrusion is ascended/descended by an ascending/descending guide protrusion according to an exemplary embodiment of the present invention.

Referring FIG. 4 through FIG. 7(c), when a user rotates a container body 100 while gripping a support body 400, an ascending/descending guide member 200 coupled to an upper portion of the container body 100 rotates together. Due to this, a pumping guide protrusion 310 which is secured at an upper side surface of an ascending/descending guide protrusion 220 of the ascending/descending guide member 200 moves along the upper side surface of the ascending/descending guide protrusion 220 and changes in height, such that the pumping guide member 300 is ascended/descended. As shown in FIG. 7(a) to FIG. 7(c), when the pumping guide protrusion 310 moves form a bottom dead point 312 of the ascending/descending guide protrusion 220 to a top dead point 311 thereof, the pumping guide member 300 ascends, whereas the pumping guide member 300 descends when the pumping guide protrusion 310 moves from the top dead point 311 of the ascending/descending guide protrusion 220 to a bottom dead point 312 thereof; therefore, the pumping guide member 300 is able to perform ascending/descending.

Meanwhile, shown in FIG. 5, when the pumping guide member 300 ascends, an internal pressure of the content inflow part 210 is changed by an ascent of the content suction tube 320 and causes a first check valve 212 to open a content inflow hole 211. This makes the contents stored in the container body 100 flow into the content inflow part 210 through the content inflow hole 211. At this time, a second check valve 331 installed at a valve installation part 330 keeps an open upper part of the content suction tube 320 closed. As the pumping guide member 300 ascends, part of the contents stored in the valve installation part 330, a content moving part 600, and a discharging tube 520 is discharged through a discharging hole 511 of the applicator 500.

Next, as shown in FIG. 6, when the pumping guide member 300 descends, an internal pressure of the content inflow part 210 changes by a descent of the content suction tube 320, and then causes a first check valve to close the content inflow hole 211. At this time, a lower end of the content suction tube 320 pressurizes an upper end of the first check valve 212, prevents the content inflow hole 211 from being opened.

At this time, the second check valve 331 installed at the valve installation part 330 by a pressure of the contents sucked into the content suction tube 320 opens an open upper portion of the content suction tube 320, such that the contents sucked into the content suction tube 320 through the open upper portion of the content suction tube 320 move to the valve installation part 330, the content moving part 600, and the discharging tube 520.

As described in the above, the present invention is configured to discharge contents by a pumping operation according to the ascent/descent of a pumping guide member 300 when a container body 100 rotates and to apply contents to lips by means of an applicator 500; thus it is possible to apply liquid contents onto lips and do a lip make-up in the same way of a conventional stick-type lipstick.
